Better than any short-range FM transmitter, you can get a hardwired Bluetooth FM modulator that plugs directly into the antenna port in the back of the radio head unit, then your stock antenna cable plugs into the modulator. The modulator picks up your Bluetooth and taps the output signal directly into the physical antenna circuit at one of (usually) two selectable frequencies on the radio dial; here's an eBay search for them . There's also similar, older-style FM modulators without Bluetooth, just an aux-in jack; these were commonly used to tap aftermarket CD changers into stock factory radios back in the day. IMO these would be preferable if your audio source (e.g. phone) has an aux-out/line-out or headphone jack. Anywhere you can eliminate a wireless signal in favor of a hardwired connection for audio, the better. Finally, if your stock head unit has a cassette player, there's also rechargeable dummy cassettes with Bluetooth built-in, so your phone would transmit a BT signal to the cassette adapter, which would then feed the audio signal right into the tape head just like playing a real cassette tape.

December 22, 2024What is the best Bluetooth transmitter for a car ?
What’s wrong with the aux? I would just use that. FM transmitters are so annoying and a true last resort. Even cassette/aux adapters are better. My previous 2006 Malibu didn’t have an aux OR cassette so I was stuck with a transmitter to play my music. Constantly fighting to find the right channel, constant static, etc. So grateful for Apple CarPlay in my new car

June 21, 2019(BIFL request) I want a good Bluetooth receiver for my car, Android compatible and the kind that connects through the 3.5mm jack, any experience?
I would look into this product (if it suits your needs). I bought a different one from them for my car (as I don't have a 3.5mm plug) and it's been flawless for a year. http://www.amazon.com/GOgroove-SMARTmini-Bluetooth-Hands-Free-Streaming/dp/B008XMV05G/ref=sr_1_4?s=electronics&ie=UTF8&qid=1421681246&sr=1-4&keywords=gogroove&pebp=1421681248997&peasin=B008XMV05G More on reddit.com

Can I use a Bluetooth FM transmitter on my boat?
As long as your vehicle has an FM radio connection and an auxiliary port, it can be used to establish a Bluetooth connection. Make sure you turn your transmitter off when not in use, as some vehicles won’t automatically deactivate them.

r/audio on Reddit: Decent bluetooth receiver for car?
June 6, 2024 -
My car has an aux port but no bluetooth. My phone has bluetooth but no headphone jack.
I used to use a USB c to headphone adaptor but every one of those I've gotten seems to have issues not including you having to unplug them when a call comes in
I'm trying to read reviews on Amazon but they seem all over the place.
I'm not trying to break the bank....but not trying to get something I'll need to replace in a week. Likewise I'm trying to avoid spending however much it would cost to replace the radio in general since idk how much longer I'll have this car. Thanks!

Aftermarket head units provide another option, with many premium models featuring advanced Bluetooth capabilities such as aptX HD and LDAC, resulting in significantly improved audio quality.
